base notes	The top of N. carcitanense subzone (basal subzone of Cenomanian) is ~99.1 +/-0.4 Ma (Obradovich et al., 2002), and cycle stratigraphy scaling of its duration (0.44 myr) and a slight offset to the GSSP marker below implies the base of the Cenomanian is 99.6 +/-0.4 Ma.				comp notes	CLARIFICATION NEEDED. This age is based on Ar-Ar ages from Japan, correlated with the European Ammonite zonation (Obradovich et al 2002), but in the spreadsheet it is shown as a fixed age in the Western interior sequence. More generally the exact logic in this area is a bit obscure, in parilcular it is not clear if the fixed age should be base saxbii, or base carcitanense
